Excess Pressure Inside a Drop and a Bubble

Excess Pressure Inside a Drop and a Bubble

The shape of a small drop of liquid can be considered spherical, neglecting the effect of gravity. This drop can further be considered as two equal hemispherical drops put together due to surface tension. The forces acting on the spherical drop are due to the pressure of the liquid inside the drop, the pressure due to air outside the drop, and the force due to the surface tension acting on the two hemispherical drops.

Behavior of Gas Molecules: Molecular Diffusion, Mean Free Path, and Effusion

Behavior of Gas Molecules: Molecular Diffusion, Mean Free Path, and Effusion

Although gaseous molecules travel at tremendous speeds (hundreds of meters per second), they collide with other gaseous molecules and travel in many different directions before reaching the desired target. At room temperature, a gaseous molecule will experience billions of collisions per second. The mean free path is the average distance a molecule travels between collisions. The mean free path increases with decreasing pressure; in general, the mean free path for a gaseous molecule will be...

Area of Science:

Colloid and Surface Science
Materials Science
Chemical Engineering

Background:

Quantifying interfacial coatings' role in foam coarsening and gas transport is challenging.
Foam coarsening and gas transport measurements often rely on assumptions about thin film thickness.
Independent quantification of film thickness and interfacial permeability effects is needed.

Purpose of the Study:

To independently quantify the effects of interfacial coatings on gas transport dynamics.
To investigate how surfactant and polymer coatings differentially affect mass transfer.
To correlate interfacial properties with foam coarsening behavior.

Main Methods:

Simultaneous measurement of mass transfer between nitrogen microbubble pairs.
Quantification of bubble volume changes over time using microscopy.
Atomic Force Microscopy (AFM) to measure film thickness and mass transfer resistances.

Main Results:

Anionic surfactants enhance mass transfer above the critical micelle concentration.
Polymer monolayers at the interface restrict mass transfer.
Interface deformation and surface force modeling align with bubble size changes.

Conclusions:

Interfacial coatings significantly influence gas transport in microbubbles.
Anionic surfactants and polymer monolayers exhibit distinct effects on mass transfer.
The study provides a method for independent quantification of interfacial effects on gas transport.
